Abstract
The invention provides a method for removing oiliness from the petrified dead catalyst, which is characterized in that: the oleaginous petrified dead catalyst, or the oleaginous petrified dead catalyst appended with water-soluble polymer dispersant which accounts for 0.5-1.0% of the weight of the dead catalyst, is heated and distilled for 60min under the pressure of 1.50-60000Pa and at the temperature of 300-600 DEG C, and then is condensed; after that the distilled oiliness is collected. The method can prominently increase the coefficient of recovery of the oiliness and reduce excessive schizolysis of the oiliness, and is particularly suitable for the recycling of the oiliness within the solids waste of oil processing.
Description
Technical field
The present invention relates to a kind of method that removes landification dead catalyst oiliness material.
Background technology
Use various types of catalyst in a large number in the petrochemical industry industry, as processes such as the various decomposition of the cracking of oil, hydrogenation refining desulfuration, alkene, polymerization, chlorination, isomerization.After catalyst uses a period of time, finally scrap the discharge system because of the catalytic activity forfeiture, the catalyst of scrapping discharge all adsorbs a large amount of oily substance of carrying under one's arms, and content reaches 20～30%.
The maximum technical barrier of the environmental protection removal process of dead catalyst is how to remove the oily substance that dead catalyst is carried under one's arms, adsorbed.At present, industrial employing high temperature incineration method is burned into gas removal with oily substance.But these oily substances are not refining crude oil completely mostly, impurity is more, add that burning facility and condition are perfect not to the utmost, make crude oil be difficult to abundant burning, the burning waste gas of discharging contains hazardous substance more, deal with the problem that equally also has atmosphere pollution improperly, burning waste gas in the practice, will to handle qualified discharge very difficult.
Patent No. CN200410021093.2 discloses a kind of dead catalyst processing method.This method is at 400～800 ℃ of following destructive distillation de-oiling preliminary treatment dead catalyst, because the pyrolysis temperature height, the oily substance cracking is serious, and micro-molecular gas output is big, and the utilization rate of oily substance is low.
Qin Yunan [" Chinese oil ", 1995,20 (3): 14-16] in the comprehensive utilization of research HYDROGENATION OF OILS AND FATS dead catalyst, adopt organic exchange extraction to reclaim grease after, handle the method that reclaims molybdenum and nickel with dilute sulfuric acid again.Report is not clearly studied the recovery of oil and the regeneration cycle of extractant, the solvent naphtha regeneration difficulty of this method extracted organic phase.
Hu Jianfeng etc. [" rare metal ", 2006,30 (5): 711-714] have proposed the comprehensive method of extracting vanadium and molybdenum from dead catalyst.They adopt organic matter extraction de-oiling pretreating process, but clearly do not study the recovery of oil and the regeneration cycle of extractant.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, propose a kind of oily substance excessive fragmentation and high method of the rate of recovery of preventing.
The technical scheme that realizes the object of the invention is as follows: oil-containing petrochemical industry dead catalyst or interpolation are by the oil-containing petrochemical industry dead catalyst of the water-soluble polymer dispersant of its weight 0.5～1.0%, at pressure 1.50～6.0 * 10
4Under 300～600 ℃ of Pa and the temperature, add thermal distillation 60min, the oily substance that condensation, collection distillate.
Described water-soluble polymer dispersant is polyphenyl olefin(e) acid, polyacrylamide, polyvinyl alcohol or polyvinylpyrrolidone.
Method of the present invention is under reduced pressure to distill, and vapo(u)rizing temperature is low, prevents that the oily substance excessive fragmentation from producing a large amount of micro-molecular gas, improved the utilization rate of oily substance.Removal efficiency 〉=99.5% of oil, the rate of recovery 〉=80% of oil, dead catalyst loss late≤3.5%.Method of the present invention can significantly improve the rate of recovery of oily substance and reduce the excessive fragmentation of oily substance, is particularly suitable for the recycling of oily substance in the PETROLEUM PROCESSING solid waste.
The specific embodiment
Measure the catalyst weight and the oil content of dead catalyst de-oiling front and back, calculate the removal efficiency of oil.Measure dead catalyst de-oiling preceding catalyst weight and oil content thereof, and the weight of the weight of recovered oil and dispersant, the oily rate of recovery calculated.By the weight of catalyst before and after the de-oiling, calculate the catalyst loss rate.Heavy oil through the oil water separator dehydration contains a spot of moisture, presses 100% oil content meter during calculating; Be easy calculating, think water-soluble polymer dispersant all pyrolysis become oil.
